Diouloulou is a small town and commune in the Bignona Department of the Ziguinchor Region of southwestern Senegal.

This was connected with the separation of the urban area from the territory of the rural community and from the arrondissement, whose main place and namesake henceforth was the village of Kataba I.

There is a small church, Eglise de Diouloulou, in the southern outskirts of the town,[5] and a campement at Auberge Myriam.

In April 2002, an MFDC splinter group, the North Front, led by Kamouguc Diatta, carried out an attack on the town, a month after assaulting Kafountine.

[7] On December 20, 2005, armed gunmen assassinated Cherif Samsidine Nema Aidara, a government ambassador to the Casamance peace process, at his home in the town.
